IPSLA SNMP OID

hi,

Is there any way to figure out which SNMP OID  is being used to monitor IPSLA jitter statistics ?

Currently, the two IPSLA operation types that have configured in the router is "path-jitter" and "icmp-echo". It seems Solarwinds is able to monitor few Jitter statistics. (Well, I dont have direct access to the Solarwinds tool out here). Here is snippet of the Solarwinds IPSLA config :-

ip sla 40006

path-jitter <IP> source-ip <IP>

vrf pub

owner SW.IpSla.VA1-SOLAR.SolarWindsOrion

frequency 300

ip sla schedule 40006 life forever start-time now ageout 0

ip sla 40007

path-jitter <IP> source-ip <IP>

vrf pub

owner SW.IpSla.VA1-SOLAR.SolarWindsOrion

frequency 300

ip sla schedule 40007 life forever start-time now ageout 0

ip sla 40010

icmp-echo <IP> source-ip <IP>

owner SW.IpSla.VA1-SOLAR.SolarWindsOrion

frequency 300

timeout 180000

threshold 400

ip sla schedule 40010 life forever start-time now ageout 3600

I wanted to view the jitter statistics by doing a snmpwalk. The problem is that snmpwalk returns back a zero for *all* the jitter related OIDs. I have been looking the SNMP object - 1.3.6.1.4.1.9.9.42.1.5.2.1.x (rttMonLatestJitterOperEntry) for the IPSLA jitter numbers. Refer to http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?objectInput=1.3.6.1.4.1.9.9.42.1.5.2.1&translate=Translate&submitValue=SUBMIT&submitClicked=true

A Cisco white paper -  Cisco IOS IP Service Level Agreements User Guide  [Cisco IOS IP Service Level Agreements (SLAs)] - Cisco Systems -  in the section - "The Cisco IOS IP Service Level Agreements RTTM on MIB" points out the following - "The Cisco Response Time Monitor MIB (Cisco-RTTMON-MIB.my) is the MIB used for IP SLAs. The only Cisco IOS IP SLAs operations that are not supported are Frame relay, Path Jitter, and ATM operations."  Am I not seeing any numbers while doing a snmpwalk through the jitter OIDs because "Path Jitter" is not supported and that happens to be the only jitter-related operation type configured in the router ?

How is Solarwinds able to gather the IPSLA statistics ? Does it use a different set of OIDs ?  How do we figure out what OIDs solarwinds is using to successfully monitor IPSLA jitter ?

Thanx !
